为进一步加强对压力管道的安全监察,确保压力管道的安全运行,根据国家质检总局《压力管道使用证登记管理规则》和《在用工业管道定期检验规程(试行)》的要求,各地都在努力开展对在用压力管道的定期检验工作。由于以前的工作中压力管道没被纳入安全监察范围,管道的安装和焊接质量没能得到有效的监督。在压力管道定期检验中,时常发现存在焊接接头未焊透现象。通过对某单位压力管道未焊透缺陷进行评级分析,本文依据《在用工业管道定期检验规程(试行)》对该未焊透缺陷进行安全等级评定是可以接受的。
In order to further strengthen the safety supervision of pressure pipelines and ensure the safe operation of pressure pipelines, according to the requirements of the Administration of Quality Supervision, Inspection and Quarantine of the People’s Republic of China on the Administration of Pressure Pipeline Registration Regulations and the Rules for Periodic Inspection of Industrial Pipelines in Piping (for Trial Implementation) Efforts to carry out regular use of pressure piping inspection. As previous pressure pipes were not included in the scope of safety inspection, pipe installation and welding quality can not be effectively supervised. Periodic inspection of the pressure pipeline, often found in the welded joints incomplete penetration phenomenon. Based on the rating analysis of impervious defects in a unit pressure pipeline, this paper based on the “Regular inspection procedures in industrial pipelines (Trial)” to assess the safety level of the impermeable defects is acceptable.
